IO Grade boundaries

Grade boundaries transform the number of marks into grades on a scale of 1-7. To determine the final grade, marks are scaled to percentages. 4 is considered passing. The individual oral counts toward 30% of the final grade at SL and 20% at HL. See course assessment for a further overview of the weighting of components. The grade boundaries are the same at SL and HL. The following grade boundaries are not official IB grade boundaries. Instead they are provided here as an indication of what can be used in class to discuss student performance.

SL / HL Marks Grade

29-33 6
24-28 5
19-23 4
12-18 3
